DEFLECTOB. FOR OIL-BURNERS;

To all whom it may] concern Be it known that I, FREDERIC A. CURTIS, acitizen of the'United States, and a resident of Toledo, in the county ofLucas and State of Ohio, have invented a certain new and usefulDefiector'for Oil-Burners; and I. do hereby declare the following to bea full, clear, and exact description oftheinvention, such as will enableothers skilled illuminating purposes, but is not restricted to suchas itmay be employed in any con nection for which it may be adapted orappropriate. a

-The object of my invention is the provision of a'single piece deflectorofthe character described, which is simple and inexpensive in itsmanufacture and construction,

is easily and quickly applied to a burner dome, and is so fashioned asto direct'the airsupply to the burner flame where it is most needed,whereby a large white flame is created and the black carbon deposits onthe chimney are entirely overcome or reduced to a minimum, thusenhancingthe efliciency,

practicability and commercial value of deflectors of this nature.

.The invention is fully described in the following specification, andwhile, in its broader aspect, it is capable of. embodiment in numerousforms, a preferred embodiment thereof is illustrated inthe accompanyingdrawings, in which Figure 1 is asectional view of a burner 1 equippedwith my invention taken on the dotted line w re in Fig. 2. Fig.2 is acentral vertical section on the line 2 2 in Fig. 1, with a part of thedeflector broken away.

Fig. 3is a perspective view of the deflector;

Figs. 4, 5 and 6 are side, top and end views thereof, respectively, andFig. 7 is a'plan of the blank from which the deflector is formed.

Referring to the drawings, 1 designates the base of a kerosene-oilburner of customary form, 2 the wick-tube rising there- Specification ofLetters Patent.

from, and 3 the burner dome, which is mountedin theusual or any suitablemanner on thebase l and has the customary flame slot or opening 1 in itstop in register with thewick-tube. The deflector-embodying my inventionis preferably stamped in a single piece from sheet-metal,and'comprisesthe two opposing substantially semi-circularsides 5, 5,and.

the parts 6, 6, which latter connect the sides at the ends of their'topor straight'edges 7 tially in parallel planes, the distance between. thesides being greater than the width of the wick-tube 2, and-the end parts6, 6 being disposed without; opposite ends of the tube top, as shown inFig. 1, to permit. the flame rising from the wick to pass freely upwardthrough the deflector opening.

The deflector blank or, disk is preferably of substantially the samediameter as the cross-sectional area of the interior of the dome 8" at,the base of the flame slot l'therein, to permit the deflector, whenmounted within the d0me, to have its ends fit closely against the domewall at the respective bases prevented from passing between the outeredges of the parts 6, 6 and the dome wall. The deflector is securedwithin the burner dome, w.in' the,presentjinstance, by ears 10,

one ofwhiclr projects outward from the outer edge of each partGcentrally thereof mounted within the dome,,has its top edgedisposed'above thev upper end of the wicktube. in'spaced relationthereto, as shown in Fig. 2.

It is found in practicethat by making the bottom edges of the deflectorsides 5, 5 of convexed form, or gradually restricted in depth from theircentral portions to the end 90. of the flame slot 4c therein, so thatthe flamefeeding air, which rises within the'dome,

parts 6, 6, the upward flow of air through the deflector to teedtheflame increases in, volume outward from the center thereof so that thegreatest volume envelops the end portions of the flame, where it is mostneeded, and effects a thorough combustion of the gases and carbonparticles at such points. The efliciency of the deflector is furtherenhanced by notching the inner-edge of each part 6 at its ends, as shownat 11 cept in so far as such limitations are specitied in the claims, asnumerous changes may be made within the spirit of the invention.

Having thus described my invention,what I claim as new, and desire tosecure by; Letters Patent, is, i

1. The combination with an oil burner having a dome and a wicktubewithin'the dome, of a deflector mounted within the dome and havingopposingdepending sides which are gradually restricted in depth fromnear the centers totheends thereof, the top portion of the'deflectorbeing'above the wick tube.

2. The combination with an oil burner having a dome and a wick tube, ofa deflector disposed within the dome and having opposing sides, thebottom edges of which substantially describe ares ofcircles, the topportion of the deflector being disposed above the wickjtube.

3. The combination with an 'oil burner having a dome and a wick tube, ofa'defiec; tor disposed within the dome and having opposing sides, thetop edges of which are substantially level and the bottom edges thereoiof arcuate form with the arcs terininating at their ends adjacentto thelevel oi':' the top edges, the top portion of the 'deflector beingdisposed above the wick tube.

A. The combination with *an oil burner having a dome and an inclosedwick tube, or a deflector encompassing the upper 1 portion ofthewvicktube in spaced relation thereto, with its top portionabove thewick tube, said deflector having opposing sides, the bottom and endedges of each of which are parts of a common arc;

5. The combination with an oil burner having a dome and an inclosed wicktube, of a deflector mounted within the dome with its upper portionabove the wick tube, said deflector having end and side portions forminga flame opening, the sides being connected by and depending from the.end portions.

6. The combination with an oil burner having a dome and a wick tubedisposed therein, of a deflector mounted within the dome with its top:portion above the wick tact 'therewith at its ends above the wick tube,said deflector having opposing sides with substantially straight upperedges and convexed lower edges, and end portions con necting the sidesin "substantially the plane of the top edges thereof.

'8. A de'flector of the class described, hav:

ing opposing sidesand encbportions connectingthe sides adjacent to theends of their top edges "and being notched at the ends of their innerside edges.

'9. Adeflector forming an air and flame opening and having the end wallsof such opening notched at the end portions thereof.

10A deflector blank of circular form having a diametrically disposedopening therein with the end walls of such'opening notched at the endsthereof.

11. A deflector blank ofcircular disk-like form'having adiametricallydisposed opening with parallel side walls and inwardlyprotuberant end walls, and ears projecting in opposed relation from theside edge'or' the blank in longitudinal register with said opening.

a In testimony whereof, I have hereunto signed'iny --name to thisspecification 1n the presence of two subscribing witnesses.
